## TEJ3M/4M – Oct 23, 2014

REMINDERS:  PARENT TEACHER INTERVIEWS  ARE OCT 23 SO PLEASE TRY TO BOOK A TIME WITH ME ASAP.  PROGRESS REPORTS WERE GIVEN OUT ON FRI OCT 17.  STUDENTS ARE TO RETURN THE BOTTOM PORTION OF THE PROGRESS REPORT ASAP (SIGNED BY PARENTS IF YOU ARE LESS THAN 18 YEARS OLD).

I began the class today by doing rebus puzzles with the students.  I did 4 of them at the start of the class.  I get the rebus puzzles from the following website:  http://www.puzzlesoup.com/ (click on “puzzles” on the left hand side, and then “search by category”).

After the puzzles, the grade 12’s (TEJ4M) were to continue with their “race bots” using lego mindstorm.  They are to build a race car of their own design that will be timed in the hall for 30 tiles (the tiles equal to 30ft in length).  On Oct 14 I gave the students 3 resources to help them better understand “Gear Ratios” which will help them design a robot that will be fast.  The 3 resources can be found below.  The students  were supposed to have their robots completed and their 3 times recorded by the end of class today but ran into a number of technical difficulties.  I told the students that I would give them extension for this activity, so they have until the end of class on Mon Oct 27.

The grade 11’s (TEJ3M) were to first make a “simple circuit” using the breadboard trainer and then they had to show it to me before moving on.  I wanted to make sure the students understood how to properly make a circuit so the LED’s would not burn out.  The students were to then make the 3 introductory circuits.  The introductory circuits they were to make on the breadboard trainer are: 1.) a series circuit; 2.) a parallel circuit; 3.) a series & parallel circuit.  I showed the students examples earlier this week on the digital projector for all 3 of these circuits.  When the students complete each of these circuits, they are to call me over to take a picture of their circuit with the iPad.   Those students that complete the 3 introductory circuits above, are to complete the next 2 circuits.  These 2 circuits are: 4.) 3 Resistors & 3 LED’s; 5.) 7-Segment LED Display.  For the “3 Resistors & 3 LED’s”, the students have to calculate the resistance for each resistor using the resistance example I gave them a few weeks ago (you will find a copy of this below).

Below you will find a copies of the handouts/worksheets that were distributed/assigned in today’s class.

A Simple Circuit Connected Properly Using Resistors on Breadboard Trainer (This is a screenshot from the live demo I did in class yesterday using the iPad)

A Simple Circuit – Using the Breadboard Trainer (Example) (this is an example of a simple circuit using the breadboard trainer – TEJ3M only)

Examples using the Breadboard (Parallel, Series & Parallel Series Circuits) (I showed this to the students in class so they knew the expectations – TEJ3M only)

Examples using the Breadboard (3 Resistors & 3 LED’s and 7-Segment LED Display) (I showed this to the students in class so they knew the expectations – TEJ3M only)

Resistance Example (the students can use this example to help them calculate the resistance of each resistor they are using for the “3 Resistors & 3 LED’s” circuit – TEJ3M students only)
